What problem does it solve? SwiftUI and UIKit code that compiles often still fails Apple's design bar: wrong spring parameters, missing haptics, poor VoiceOver support, wasted iPad layout space, and Dynamic Type breakage. This Skill audits existing iOS UI code against Apple-native quality standards and produces a unified, severity-ranked report. ## Core Features & Use Cases - Parallel specialist review: Dispatches three agents covering visual design (HIG, Liquid Glass, typography, layout), animation and haptics (spring physics, Reduce Motion), and accessibility (VoiceOver, Dynamic Type, contrast, touch targets). - Unified severity-ranked report: Merges and deduplicates findings into per-dimension verdicts (HIG, animation, haptics, accessibility, adaptive layout) with concrete SwiftUI rewrites and top-3 priority actions. - Delta tracking across runs: Writes a review ledger to .claude/apple-ui-craft/last-review.json and reports findings as NEW, RESOLVED, STILL OPEN, REGRESSED, or IMPROVED versus the prior run. - Use Case: After building a new settings screen, run the review on the diff before claiming the work done; it flags a missing Reduce Motion fallback, a 40pt touch target, and a non-adaptive iPad layout with fixes for each. ## Quick Start Ask the assistant to review my iOS UI changes for Apple-native quality, or pass a scope such as a file, directory, "staged", or "all".
